on a drive shaft 15, the latter being supportedin bearings lfi vhich maybe secured on the -machinesj 1,2. The shaft 15 is connected to a suitable drivingmech- "anism; and when operated willzcause the ad acent s des of the belts 1 O- tatraveleimul- ;taneously1n the same direction.

Ar nge ve e mac ines 5, nd the space between the' nachines, is, a track V 17 upon which travels a pair ci e-trolleys 18, and, suspended frorn-v each zof theitrolleys 18i is a yoke l9 havinglvattached thereto, V q-through a-threa'dedadmsting screw 21, a 4.0 i-g.; 2. 1s awfrontwelevation partly in sec--% support 20.

Qjournaled in brackets 25, fixed tothe sup- 1 ports 20. Theshaft 24: projectsoutvvardly from one; of the gyokes. 19. and'is provided with a hand Wheel 26 forturninggitto adjust the supports verticallyineither direchalf. The shaft 27 carries. aseries of hangt ers 28 formed WithQthrea-ded openings 29 :fo eng g g-W t t athreads cfzi-theshef 27. The hangers 28 have sliding engagement intermediate their ends with guide rods 30 and 31 which are supported on the parts by means of brackets 32. The shaft 27 is provided with an operating wheel 33 When rotated in one direction, the hangers 28 will be moved toward each other and when revolved in the opposite direction will be moved away from each other. The lower end of each of the hangers is inturned as at 33 and constitutes what may be termed a supporting ledge. The hangers 28 is to engage under the pallets 34 which support the molded block or article and elevate the pallets with the molded article from the machine and transport them to plank 12.

When the hangers 28 are positionedbelow the pallets 34, the wheel 26 is rotated in one 71 directionwhereby the hangers are elevated and the pallets with the molded articles lifted from the molding machine. By revolving the wheel 33, the shaft 27 is re- I volved and the hangers 28 and the pallets 34 thereon are brought close together. By this arrangement provision is made for properly positioning the pallets on the planks or trays 12 so that they can enter a curing chamber if the latter should be narrower than the distance between the pallets when taken from the machine, and provision is also made, whereby if desired the pallets can be separated. Primarily the adjustment of the supporting elements is to reduce the distance between the pallets to en able a reduction in steam or curing room space.

arm 46, carrying a pulley 47 over which \Vhen the hangers 28 have been adjusted to desired position, the transporting mechanism is shifted upon the track 17 to a posi tion over the plank 12. The wheel 26 is then revolved so as to lower the hangers 28. The planks 12 are narrow so that-the ledges 33 will pass downwardly along the edges of the same and deposit the pallets 34 on the planks.

Arranged over the track 17 and disposed at right angles with respect thereto is a track 36, upon which is mounted a trolley 37 having a supporting yoke 38 depending therefrom and extending through the base of said yoke is a vertically disposed rod 39 having a head 40 at its upper end and surrounding said rod 39 and interposed between the head 40 and the base of the yoke 38 is a resilient support 41 in the form of a coiled spring.

Vertically movable upon the rod 39 is a carrier frame 42, the latter being connected to the rod 39 by the sleeves 43. The carrier frame 42 includes a series of tiers of supporting brackets 44 for the planks 12 when carrying the latter to the curing chamber 45. Depending from theyoke 38 is an function of the rod 39 is also'provided with guide members 50.

The track 36 extends into the curing chamber 45 and the inner faces of the side walls 51 of the curing chamber 45 are provided with guideways 52, for the guide members 50 and ledges 53 for supporting planks 12. I

It will be assumed that the hangers 28 have positioned a plurality of pallets with the molded articlesupon the upper plank 12, the belts 10 are shifted to lower the loaded plank, and another; plank isplaced upon the next pair of strips 11. Another set of pallets with themoldedi articles are set upon the last mentioned plank. The belts 10 are again operated to lower the two loaded planks. *This operation is continued until the desired number of planks are arranged on the belts 10. As illustrated, the carrier 42 is constructed to convey 4 planks simultaneously from the belts 1 into the curing chamber, but this number The trolley 37 is shifted on track 36 to position brackets 44 beneath the planks 12 on the belts 10 and then the carrier 42 is lifted by means of rope 48 to remove the planks from the belts. The carrier is then shifted away from the belts, the rod 39turned and thecarrier then shifted into the curing chamber to position the planks upon the ledges 53. When the carrier is shifted into the-curing chamber the guide members 50 travel in guideways 52 therebypreventing any lateral shifting of a carrier. At the desired point the carrier is lowered until the planks engage the ledges 53 and is then removed from the drying chamber.

In Fig. 5 of the drawings, a modified-form of carrier is illustrated which consists of a truck 54, provided with an upright frame 55 carrying supports 56 for the planks 12. The supports 56 are positioned below the planks, the truck is tilted andthe' planks can then be removed from the strips 11 and with the molded articles thereon transported into the drying chamber and deposited upon the ledges 53.

What I claim is:

1. In apparatus of the class described th combination of a frame adapted for movement along a trackway, a plurality of vertically arranged screws thereon, means whereby said screws are rotated in unison, supports carried by said screws, a horizontally arranged screw carried by said supports, and one or two article carriers on the last-mentioned screw and adjustable horizontally thereby. 1

\ whereby said screws are rotated in unison,

carriers on said means and adjustable horizontally thereby.

In testimony whereof I afiix my signature in the presence of two witnesses.

ALBERT A. PAULY.
